Answer: y = 4x
Step-by-step explanation: Slope intercept form is y = mx + b where m is the slop and b is the x intercept
We can solve for slope using the given points
(2-1)/(8-4) = 1/4, thus m = 1/4
y = 1/4x +b
Now to solve for b, we can just plug in one of the points to see what makes b work
1 = 4*(1/4) + b
1 = 1 +b
b = 0

A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?
Answer:
The equation that will represent the number of grams present after n hours is [tex]A(n) = 150(0.85)^n[/tex]
3.035 grams will be left one day from now.
Step-by-step explanation:
Exponential equation for the amount of a substance:
The exponential equation for the amount of a substance is given by:
[tex]A(t) = A(0)(1-r)^t[/tex]
In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time period.
A radioactive isotope is decaying at a rate of 15% every hour.
This means that [tex]r = 0.15[/tex]
Currently there are 150 grams of the substance.
This means that [tex]A(0) = 150[/tex]
Write an equation that will represent the number of grams present after n hours.
[tex]A(n) = A(0)(1-r)^n[/tex]
[tex]A(n) = 150(1-0.15)^n[/tex]
[tex]A(n) = 150(0.85)^n[/tex]
How much will be left one day from now?
One day is 24 hours, so this is A(24).
[tex]A(24) = 150(0.85)^{24} = 3.035[/tex]
3.035 grams will be left one day from now.

Connor’s temperature was 0.7 degrees higher last night than it was this morning. His temperature this morning was 101.2 degrees. What was his temperature last night?
Answer:
101.9 degrees
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Let's define what we have:
Conner's morning temperature: 101.2 degrees
Conner's last night temperature: morning temperature + 0.7 degrees
We know that Conner's last night temperature is addition because it was higher (key word) than the morning temperature.
Therefore, we simply add the values together to get our answer:
101.2 + 0.7 = 101.9 degrees

If an exterior angle measure of a regular polygon is 60°, how many sides does the polygon have? What is the measure of each interior angle?
9514 1404 393
Answer:
6 sides120°Step-by-step explanation:
The sum of the measures of the exterior angles of a convex polygon is always 360°. If each is 60°, there are 360°/60° = 6 of them.
There are 6 sides.
The adjacent interior angle is the supplement of the exterior angle, so is ...
180° -60° = 120°.
Each interior angle measures 120°.
A perfume manufacturer puts 16 fluid ounces in each bottle. How many gallons will fill 96 bottles?
Answer:
12,228 ounces
Step-by-step explanation:
There are 128 ounces in a gallon. So multiply 128 ounces by the number of gallons.
128 x 96 = 12,228
96 bottles of perfume will fill 12 gallons.
Given that a perfume manufacturer puts 16 fluid ounces in each bottle.
We need to find how many gallons will fill 96 bottles,
To find the total number of gallons required to fill 96 bottles, we need to calculate the total volume in fluid ounces and then convert it to gallons.
Given that each bottle contains 16 fluid ounces, the total volume in fluid ounces for 96 bottles can be calculated as:
Total fluid ounces = 16 fluid ounces/bottle x 96 bottles
Total fluid ounces = 1,536 fluid ounces
To convert the total volume from fluid ounces to gallons, we use the conversion factor:
1 gallon = 128 fluid ounces
Therefore, the total volume in gallons is:
Total gallons = Total fluid ounces / 128 fluid ounces/gallon
Total gallons = 1,536 fluid ounces / 128 fluid ounces/gallon
Total gallons = 12 gallons
So, 96 bottles will fill 12 gallons.

3x-4y=-2
3y-2x=1
Answer:
y = -1, x = -2
Step-by-step explanation:
First, multiply the top equation by 2 to make 3x become 6x:
6x - 8y = -4
Second, multiply the bottom equation by 3 to make -2x become -6x:
9y - 6x = 3
Add the two equations together, and you get:
y = -1
Plug in y as -1 into the first or second equation:
3x - 4(-1) = -2
OR
3(-1) - 2x = 1
x = -2

Use the number line to answer the questions that follow
Answer:
A. make a point on the line to the right 2 units from 0
B. the opposite of 2 isn't located at the same place as point P on the number line because the opposite of 2 is -2 and the point P is the opposite of negative 2 which would be positive 2. So the two points are not in the same place because they have different signs.

find the area of the figure below, composed of a rectangle with two semicircles removed. Round to the nearest tenths place.
Answer:
Area of figure = 11.43 unit² (Approx.)
Step-by-step explanation:
Given:
Length = 6 unit
Width = 4 unit
Radius = 4/2 = 2 unit
Find:
Area of figure
Computation:
Area of figure = Area of rectangle - 2[Area of hemisphere]
Area of figure = [l x b] - 2[(πr²)/2]
Area of figure = [6 x 4] - 2[(3.14 x 2²)/2]
Area of figure = 24 - 12.57
Area of figure = 11.43 unit² (Approx.)

Answer:
Must understand distance and slope formula first:
slope y_2-y_1/x_2-x_1
distance d=√((x_2-x_1)²+(y_2-y_1)²)
(Just search up the formulas if this isn't clear)
Step-by-step explanation:
For #13 take two points and put them in the distance formula remember (#,#) the first # is 'x' the second # is the 'y' in a point.
then you could simply type all that in a calculator and a single number should pop up indicating one of the lines (doesn't matter the #) then do the same for the second points (cuz you used two already you have two left) If the number is same as the first two points it's a pallelagram. (I tested it out got 7.07...)
For the slope you're doing something similar to the distance formula, you're filling out two sets of points into the slope formula if they come out the same # it's parallel.

Why can you double the volume of a right prism by doubling either the height or the area of the base?
Answer: You can double the volume of te right prism by doubling either the height of the area of the base because if you do that it will either get double the height, therefore being double the size, or double the width, therefore being double the size as well. So the volume will also be double.
